JAMES I-I. SMITH, OF BELLEVILLE, ILLINOIS.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 537,368, dated April 9,1895.

Application fled October l, 1894.

To @ZZ whom it may concern:

Be it known that I, JAMES Il. SMITH, of Belleville, St. Clair county,Illinois, have invented a certain new and useful Improvement inLubricators, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification.

My invention relates to'that class of lubricators employed to supply oilto steam pipes forbthe purpose ot' lubricating steam engine cylinders,the., and my invention' consists in features of novelty hereinafterfully described and pointed out in the claims.

Figure I is a side elevation. Fig. II is an end view. Fig. III is avertical section taken on line III-III, Fig. II. Fig. IV is a horizontalsection taken on line IV-IV, Fig. I. Referring to the drawings: 1represents the oil vessel, composed of a central cylinder 2 and endshells 3 and 4. At two sides of the cylinder 2 is an inlet steam pipe 5and an outlet steam pipe 6, from and to which steam is carried throughthe lubricator.

7 are ports leading through the cylinder t form communication betweenthe inlet and the outlet steam pipes.

In the interior of the cylinder 2 are two annular anges 8 provided withopenings 9 and fitting inside of said iianges is a bushing 10, .betweenwhich bushing and cylinder an annular space 11 is formed. In the bushing10 is a plug valve 12 in which is an opening 13 arranged to registerwith the ports 7 in the cylinder 2 to allow the passage of steam fromthe inlet steam pipe to the outlet steam pipe. The valve 12 is providedwith a stem 14 that extends to the exterior of the lubricator at oneend, and is provided with a handle 15 by which the valve may be turnedto open or close the steam passage through the lubricator.

Secured to the nipple 4a on the end shell 4 is a quadrant 16 providedwith a number of depressions 17, and in the handle 15 isa set screw 18whose point is adapted to fit in any one of said depressions to retainthe handle in a Xed position, either with the valve 12 turned toentirely close ed the passage of steam through the ports 7 or turned sothat the passageway is completely or partially open, according to theamount of steam desired to pass through.

Serial No. 524,573- (No model.)

In the end shell 3 is an oil hole that is closed by a screw plug 19.

Leading from one side of theh interior of the cylinder 2 into the outletsteam pipe (i is a conical valve opening 20, and 2l is an independentscrew valve located in the same plane as the steam-passage, arrangedtangentially thereto and provided with a conical point 22 adapted toseat in the valve opening 20.

In the operation of the lubricator the oil vessel is filled with oil,and steam is permitted to pass from the inlet pipe 5 to the outlet pipe6, on turning the valve 12 so that the Opening 13 registers with theports 7. The valve 21 is then opened and the steam in passing into theoutlet pipe draws the oil, by suction, from the annular space 11 in theinterior of the cylinder 2 and is carried with the steam to the enginecylinder or other part to be lubricated.' To overcome the vacuum thatwould otherwise result in the annular space 11 and prevent the flow ofthe oil through the valve opening 20, I provide a check-valve 23 at theside of the port 7 next to the inletsteam pipe, which check-valve isdrawn open by the force ot' the steam in moving past it, and the steamis permitted to enter through the opening into the annular space 11, andsuch admitted steam condenses to water and falls to the lower end of thelubricator vessel and acts to elevate the oil. The check-valve 23 isprovided with a spring 24 that closes the valve when the steam draft isnot exerted to hold it open. The valve 23 is seated in a bushing 25, andsaid bushing is inclosed by a screw cap 26. Secured to the end shells 3and 4 are common valve nipples 27, between which is located the sighttube 28, the passages from the shells to the sight tube being controlledby the cone point valves 29.

30 is a valve, which in the position in which the lubricator is shown inFigs. I and III, is employed in draining the oil vessel of the wateraccumulated therein from the condensing of the admitted steam. Thelubricator is, however, capable of use with either end uppermost, andwhen the position is reversed from that shown in Figs. I and III thevalve 30 is employed in filling the vessel 1 and the oil hole 19 isemployed as a draining valve.

I claim as my invention- 1. The combination of an oil vessel, a steamIOO passage through said vessel, a V'alve controlling said passage, andan independent Valve arranged tangentially to the steam-passage and inthe same plane as the latter and forming communication between theinterior of said oil vessel and said steam passage; said independentvalve permitting a constant suction and passage of Vapor and anindependent regulation of the flow of the oil, substantially asdescribed.

2. In a lubricator, the combination of an oil Vessel, a steam passagethrough said Vessel, a valve controlling said passage, a Valve form. ingcommunication between the interior of said oil Vessel and said steampassage, and a check valve opening from said steam passage into theinterior of said oil vessel, said check Valve permitting of a low ofpressure to said oil vessel for the purpose of avoiding Vacuum thereinsubstantially as described.

3. In a lubricator, the combination of an oil vessel, a steam passagethrough said vessel, perforated anges 8 on the interior of said Vessel,a bushing seated within said ilanges, a Valve in said bushing arrangedto register with said steam passage, and a Valve forming communicationbetween the interior of said oil vessel and said steam passage,substantially as described. v

4. In a lubricator, the combination of an oil vessel, a steam passagethrough said vessel, perforated flanges 8 on the interior of saidvessel, a bushing seated within said flanges, a Valve in said bushingarranged to register with said steam passage, a Valve formingcommunication between the interior of said oil vessel and said steampassage, and a cheek valve openingfrom said steam passage into theinterior of said oil vessel, substantially as described.

5. In a lubricator, the combination of an oil Vessel, a steampassage-way through said Vessel, a valve arranged to control saidpassage- Way; said valve being provided with an opening capable ofregistration with said passageway, an independent Valve arranged tocontrol an opening from said oil vessel into said passageway, whereby aconstant flow of oil is induced to How from said oil vessel into saidsteam passageway; substantially as set forth.
